IMPRQVEMENT IN RQTARV ENGINES.

Specification forming part of Letters Patent No. 123,575, dated February 13, 1872 antedated January 29, 1872.

CASE B. To all 'whom it may concern:

Be it known that I, Gmnon B. MAssnY, of the city of New York, in the county and State of New York, have invented a new and useful Improvement in Rotary Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

The object of this invention is to furnish an engine to work upon the rotating principle which shall not be subject'to the ruinous friction of ordinary rotating enginesdesigned more especially for the application of steam as a motive power, but is not confined exclusively thereto 5 and it consists in the construction,

arrangement, and combination of parts, hereinafter described.

In the accompanying drawing, Figure 1 is a vertical section of Fig. 2 taken on the line ma, showing the stationary cylinder, the pistons, and the revolving piston-wheel. Fig. 2 is avertical section of Fig.1 taken on the lineyy, showing the interior of the engine in crosssection.

Similar letters of reference indicate corresponding parts.

is made fast to the shaft, and acts as a crank to carry the shaft 0. The pistons F are attached to the shaft by eyes, so that they turn freely thereon. G represents packing pieces confined in circular recesses in the pistonwheel, between which pieces the pistons work.

The piston-wheel revolves, in the position seen in Fig. 1, in a shallow recess in each of the cylinder-heads and concentric with an inner circle; seen in dotted lines in the same figure.

The periphery of the pistonwheel, it will be seen, works steam-tight, or nearly so, with the upper inner surface of the cylinder, and being carried around its own center by the action of the steam on the pistons it slides on the pistons as the ends of the latter sweep the interior surface of the cylinder, and receive and exhaust the steam. During each revolution it will be seen that the pistons F necessarily change their radial positions, but their packin g pieces Gr turn in the recesses and thereby allow the pistons F to alter their radial lines while the packing remains steam-tight.

H is the induction-port, and I the eduction or exhaust port. These ports are long slotholes in the cylinder, covered bythe steam andexhaust pipes J K. L is the driving-pulley.

By this arrangement it will be seen that the pistons are constantly taking steam, so that the power applied to the shaft is nnremittin g, and that the cylinder is constantly exhausting steam.

The operation is plainly seen in Fig. 1.

I do not confine myself to any particulars as regards the details of construction or mode of preserving all the joints steam-tight.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In combination with cylinder A, having shaft 0 through the center thereof and pistonwheel E, the fastpiston F and loose pistons F passing through the paokings G, as and for the purpose specified.
